COMPOUND LEVER.

SPECIFICATION forming part of Letters Patent No. 251,681, dated December 27, 1881,

I Application filed November 16, U381. (Model) To all whom it may concern Be it known that we, JESSE HIATT and NICHOLAS HIATT, of Independence, in the county of Montgomery, andin the Stateof Kansas, haveinvented certain new and useful Improvements in a Compound Lever for a Brick- Machine, and for all other machines, tools, and instruments where leverage power is used; and we do herebydeclare the following is a full, clear, and exact description thereof, reference being bad to the accompanying drawing, and to the letters of reference marked thereon, making a part of this specification.

' This invention relates to certain improvements in compound levers for operating brickmachines, cotton-presses, and other similar apparatus; and it has for its object to provide a strong and efficient apparatus, whereby powerful leverage maybe secured. These objects we attain by the apparatus illustrated in the accompanyingdrawing, which represents a perspective view of our invention.

The letter A indicates the base of the apparatus, which may be constructed of wood or other suitable material, upon which are mounted the two parallel frames B, constructed pref erably of wrought-iron in the form shown. Between theupper ends of the said frame is fulcrumed a lever, O, the short arm of which projects beyond the frame, and is provided with a recess, D, to form a lifting device. The

long arm extends backward, and is provided with a vertical arm, D, and is bifurcated, as indicated by the letter E. The arm D is intended to be employed in such machines in which a downward pressure is necessary. The lever G is provided with a grooved frictionroller, F, at its extremity.

The letter G indicates a lever fulcrumed at H between the frames. The said lever on its upper side is provided with ways I, consisting of rods of iron or other material of proper size, which are bent as indicated, and secured to the lever in any suitable manner. The said ways embrace the friction-roller, which is adapted to travel back and forth between them as the lever G is oscillated, actuating the lever G, the two levers forming a powerful compound lever, which operates with comparatively little friction, and which is strong, durable, and not liable to getout of order. The bifurcated portion E of the lever 0 may be carried down below the lever G, and may have the frictionroller so located as to travel on a single guide attached to the lower side of the said lever, or between double guides secured to the lower side of the same.

Having thus described our invention, what we claim, and desire to secure by Letters Patent, is-

A compound lever consisting of a lever, O, having a recess, D, and an arm, D, a bifurcated extension, E, a friction-roller, F, and le-' ver G, fulcrumed at H to the frame B and provided with ways I, the whole adapted to operate substantially as specified.

In testimony whereof we affix our signatures, in presence of two witnesses, this 28th day of September, 1881.

JESSE HIATT. NICHOLAS HIATT.
